You'll be amazed at what structures actually exist at the molecular scale. Yes, each of these structures is real! Step inside for a closer look.

These mighty miniature motors convert chemical energy to mechanical work! See proteins that walk or can move huge masses.

We can perform reactions in our bodies that require harsh conditions in the macro world. Did you ever wonder how we can extract energy from food at much higher efficiency than an automobile, yet we are able to operate at a much lower temperature? You can thank enzymes for this and much, much more.
